I had a similar issue -- In our case I think it was graphs not updating, but devices still reporting as up.
We ended up just running the poller (that's usually run via cron) by hand and looking at the output. I believe there were a couple of missing dependencies that we needed to install relating to python and mysql. But, it's been several months so my recollection is a bit fuzzy.
